Is this sentence correct?
Once you'll figure out how this works, you'll love it
What I am trying to convey is:
The person that I am addressing does not understand a certain concept. I want to tell that person that once he/she understands that concept, he/she will love it.
I am not sure about the tenses. I am using Future Simple in both parts of the sentence. Is this OK? Should I use Present Simple in the first part:
Once you figure out how this works, you'll love it
Which one is correct? (Or at least better)
